Description

Device for discharging combustion products

The invention relates to a device for discharging combustion products for a furnace having a flue pipe. More specifically, the invention relates to improvement the removal of combustion products in sealed gas devices for hot water preparation, which are provided with a pull-off are.

It is known that in such cas hot water heaters Combustion chamber is connected to the environment of the room in which the device is located by two lines, as a rule are arranged concentrically to one another. One of the lines supplies the burner with the air required for combustion, the other line carries away the burned cases that were incinerated. These two lines penetrate the wall of the room and are covered at their end facing the ambient air by a baffle arrangement that ensures correct circulation the fresh air and the burned gases.

As already stated above, the two lines are at the known triggers are generally arranged concentrically to one another. Such an arrangement leads to good results, as regards the flow of fresh air and burned gases. However, this arrangement cannot be used flexibly because the The outlet opening of the forced ventilation provided on the furnace must be very precisely aligned with the pipes of the Abzuas. One must therefore each time the fan to discharge the combustion gases to the required type of exit leading to the outside adjust: upwards, backwards, to the left or to the right, depending on where the most favorable point is

crossing wall or wall.

It has already been proposed to pull the blower off to provide the combustion gases with an outlet that can be oriented in such a way that the pre-combustion gases are discharged in the same way can be done on any of the sides of the furnace or on its top. Rei such known arrangements the outlet is in the form of an orientable pipe bend. In this way, the desired goal is achieved, this solution however, it has the disadvantage that an intervention in the interior of the device is necessary.

The present invention is intended to provide a solution by means of which this disadvantage is eliminated.

The invention consequently relates to improvements in devices for removing combustion products from devices in which a fuel is burned. In particular, it relates to sealed ones Gas devices, e.g. gas hot water heaters, which are provided with a fume cupboard. The solution according to the invention exists in that the output of the exhaust of the combustion gases The fan used is provided with a distributor in the form of a cross-shaped pipe arrangement. With this pipe arrangement the gases fed in through an inlet can exit from one of the three outlet openings of the pipe arrangement; the the other two outlet openings are closed. In this way the combustion products can optionally be carried out in one of the the three outlets can be deducted from the given directions.

If the Ausl aßö-Ffunrr is not arranged on the device axis, so have the right according to an advantageous further development of the invention Pohr and the left pipe of the cross-shaped pipe arrangement are different

explained in more detail with reference to the accompanying drawing. In this show:

1: a sectional plan view of a hot water heater with forced discharge of the combustion products;

FIG. 2: a view similar to FIG. 1, but with a Another embodiment of the invention is shown; and

FIG. 3: a view similar to FIG. 1, but in which a other type of connection is indicated.

In Fig. 1, a sealed hot water heater 1 is shown, which is provided with a fan 2, which ensures the forced removal of the combustion products. The discharge The combustion products take place via an exhaust system 3 which penetrates the wall 4 of the room in which the hot water heater is located is arranged.

At the outlet of the fan 2 used to discharge the combustion products, a cross-shaped distributor 5 is provided, Via which the combustion products can be discharged in any of the directions specified by lines 6, 7 and 8 can be. The lines 6, 7 and 8 represent a part of the cross-shaped distributor 5. Not for discharge the lines used for combustion products, in the case of the one shown Embodiment these are the lines 6 and 7, are closed using plug-shaped covers 9. The latter are provided with a resilient seal 10, which ensures a fluid-tight connection.

As a result of this arrangement, depending on the situation, only one of the three outlet openings of the distributor 5 needs to be opened and only the outlet pipes need to be connected to this opening to become.

The one in Pig. The embodiment shown in FIG. 2 can be used in the case in which the outlet of the fan 2 ' serving to discharge the combustion gases is not arranged on the device axis. In this embodiment, the right line 8 ¹ and the left line 6 ^{1 of} the cross-shaped distributor 5 'have different lungs.

The cross-shaped distributor arrangement 5 or 5 ¹ , which is provided on the fan serving to discharge the combustion gases, can be produced in various ways. It can be composed, for example, of two symmetrical shells that are curved and mechanically connected to one another or are welded. These shells can either be cast or consist of rolled and flanged tubes.

The shape of the cross-shaped distributor can also be chosen so that there are transition radii between the individual lines which facilitate the flow of gases.

From the above description it can be seen that using a device according to the invention for discharging Combustion products a device producing combustion gases with forced discharge of the combustion gases in any way with fume cupboards that are either behind the device or on any of its sides. The use of the device can be done without any intervention in the interior of the device is necessary.

In Fig. 3, another type of connection is that of the invention Device shown. With this modification, the combustion gases are discharged on the rear side of the one generating them Device, using line 7 "and lines 6" and 8 "in the manner already described above are locked.

It goes without saying that the present invention is not restricted to the exemplary embodiments described above and shown in the drawing, but rather all modifications are included closes.
